I had a running armbian kiosk. Today I switched it from external USB modem to internal wifi connection. And it started to behave faulty. Like not playing videos and freezing.

So I shutted it down and took it home.
At home I decided to rewrite it with a fresh image.
I started parallels->windows with burning rom 2.1.2 running. And plugged vim usbc to my mac with my finger on vim’s Power button as I remembered it could bring it to upgrade mode instantly(looks like its not).

Vim just turned red light on and that’s it.
I tried to attach a serial console but nothing is there at all. Not a single line.

I tried resetting it with Reset button, Power+Reset, M-register mode with no luck.
Still red light and no console output.
What can be wrong?
